Loop heat pipe

1. A loop heat pipe, comprising: an evaporator having an evaporator body made of a heat conductive material, the evaporator body comprising at least two retaining holes and at least a channel hole penetrating the retaining holes; and a sealed pipe comprising at least two sealed ends, the two sealed ends being securely fastened to the two retaining holes of the evaporator; wherein at least one of the two retaining holes is a through hole, which penetrates through two sides of the evaporator body, and at least one of the sealed ends protrudes the evaporator via the penetrable retaining hole, wherein the sealed pipe comprises two or more pipe bodies sequentially connected with each other, and wherein the pipe bodies are connected via a connection piece, the connection piece including two connection holes for penetrating therethrough the pipe bodies and a channel hole that penetrates the connection holes.

2. The loop heat pipe as recited in claim 1 , wherein the evaporator body is made of aluminum or copper.

3. The loop heat pipe as recited in claim 1 , wherein the evaporator body comprises a contact surface for contacting a heat source.

4. The loop heat pipe as recited in claim 1 , wherein a sealed portion is formed on the top portion of the evaporator body at the channel hole of the evaporator.

5. The loop heat pipe as recited in claim 4 , wherein the sealed portion is a plug, or a soldered structure formed by a soldering procedure.

6. The loop heat pipe as recited in claim 1 , wherein the sealed pipe is a bent pipe body.

7. The loop heat pipe as recited in claim 6 , wherein the sealed pipe is bent to a U-shape.

8. The loop heat pipe as recited in claim 1 , wherein a sealed structure is formed at the sealed end that protrudes the evaporator.
